Розраховано середньодобові концентрації шкідливих домішок та їх перевищення гранично допустимих концентрацій. Зроблена оцінка впливу напрямку та швидкості вітру на концентрацію різних забруднюючих речовин.One of the important tasks in the system for monitoring the purity of atmospheric air is the study of the mode of formation of harmful impurities and the calculation of their transfer, depending on the nature of atmospheric circulation and local physical and geographical conditions. Modern cities occupy large areas and therefore changes in the concentration of pollutants in the air are determined by meso- and macroscopic processes and meteorological conditions. According to many researches, the concentration of harmful impurities mostly depends on the wind regime. The goal of this research is to study the wind regime on individual control and measuring posts of Odesa and its influence on the concentration of various pollutants in the winter and summer seasons. The calculations and analysis was made on the example of data of four-time observations in 2009 on three control posts located in different districts of Odessa. The recurrence of velocities and wind directions was calculated, and wind roses was constructed for all summer and winter months. The average daily concentrations of pollutants: dust, sulfur dioxide, carbon monoxide, nitrogen dioxide, phenol, soot and their excess of maximum permissible concentrations were calculated for the estimation of pollution levels of the Odessa air pool. A comparative analysis of the levels of air pollution at the posts was made in conjunction with the regime characteristics of the wind. Research have shown that the wind regime is significantly different in the considered posts both in the dominant directions, and at the speed of the wind. The proximity of the seaside and dense of urban development creates conditions for changing the velocity and the direction of the wind, and also causing the formation of local circulations, which in turn significantly affect the pollution of urban air. The concentrations of all types of impurities in the territory of the Odessa city increase with the distance from the coastal strip to the depths of the land. To identify the role of synoptic conditions in the formation of elevated levels of pollution used types of synoptic situations. The results of a coherent analysis of synoptic maps and data with the concentration of these substances during the winter and summer seasons show that for most pollutants, both in winter and summer seasons, the excess of maximum permissible concentrations is observed in peripheral processes with low-gradient pressure fields, in the anterior parts of cyclones and in slow-moving and small-sized cyclones with the same air mass.ukрежим вітрурівень забруднення атмосферигранично-допустимі концентраціїwind regimeatmospheric pollution levelmaximum permissible concentrationСтаття
